(54) | High resolution optical fiber array and article position determining system |
(57) A vision apparatus for indicating the locations of edges of work pieces in an illuminated
work area including several arrays where each array includes several light conducting
fibers. One end of the array is positioned in the work area to be illuminated by light
except when blocked by the object. The other end of the optical fibers are positioned
in a matrix plate contained within a camera enclosure. The camera enclosure further
includes a lens to optically couple light from the matrix plate optical fiber ends
to a light sensing device that produces electrical signals indicating the presence
or absence of light at each of the fiber ends. |
